Dave,

That idea is not at all nuts! That little bit of flotation on the end of a mast will give you the equivalent of about 7 or 8 cubic feet of foam inside the cabin, in terms of righting moment. It should prevent the boat from turning turtle.

Alternatively, you could put some foam inside your mast up at the top, and avoid the windage...

BTW, I'm the person who put 1" foam on the cabin ceiling. The reason for doing so was to cover up all the bolts inside my cabin top. They were a safety hazard! There are about 60 or 70 bolts thru my cabintop for the genny tracks (34), deck organizers (8), rope clutches (14), and winches (6), large horn cleats (4).

Additional floatation was just a minor side benefit. If I ever turtle it with the boards out, it may be a benefit... but mostly, I didn't want people cutting their scalps on the nuts and bolts.

Best,
